Erro gerando build do web app

[vgeorge]

Seguindo os passos de instalação, o grunt dá erro ao não encontrar o módulo 'angular-cookie'. Lembro que havia uma maneira de instalar manualmente, mas não encontrei a documentação. Este é log do erro:

>> Error: Cannot find module 'angular-cookie/angular-cookie' from '/Users/vgeorge/dev/mapascoletivos/webapp/tmp/app'
Warning: Error running grunt-browserify. Use --force to continue.
